Definitions

  • This invention relates generally to a turbine used in vapor stream in a chemical processing or refining plant, and more particularly to a turbine used with a vapor stream that is at or near its dew point.
  • Control valves are used to control the flow, upstream or downstream pressure, temperatures, or levels, etc.
  • mechanical energy is dissipated. Since the energy is dissipated, without recovery, the energy is lost.
  • the turbine could potentially be problematic. Specifically, in a vapor stream at or near its dew point, when the vapor stream passes through the turbine and its pressure is reduced, the resultant vapor stream will partially condense forming a two-phase stream as a result of the cooling of expansion of the vapor. While there are currently turbines that are designed to accommodate the two-phase stream, such turbines are complicated in design and difficult to predict in operation.
  • the present invention attempts to overcome one or more shortcomings discussed above.
  • upstream of the turbine is a supersonic separator which separates out the heavier components before the vapor stream is passed to the turbine.
  • the supersonic separator imparts a swirl at sonic or supersonic velocity to the vapor which condenses some of the heavier compounds into droplets.
  • the droplets are separated from the remaining vapor phase components which are then passed to the turbine for a pressure reduction while generating electricity.
  • the turbine is able to provide information about the amount of energy removed. This information may be utilized to in determining adjustments for various processing conditions which reduce the amount of energy added to the process. This permits the processor to more efficiently operate the processing unit without reducing the throughput of the processing unit.
  • the present invention may be characterized, in at least one aspect, as providing a process for recovering power from a vapor stream with a turbine by: condensing a portion of the vapor stream in a supersonic separation device, the separation supersonic device configured to impart a swirl at or above a sonic velocity on the vapor stream passing therethrough; separating the condensed portion from the vapor stream with the supersonic separation device to provide a superheated vapor stream; and, recovering power from the superheated vapor stream in a turbine, the turbine comprising a turbine wheel configured to transmit rotational movement to an electrical generator.
  • the present invention may be generally characterized as providing a process for recovering power from a vapor stream with a turbine by: passing a vapor stream to a supersonic separation device, the supersonic separation device configured to impart a swirl at or above a sonic velocity on the vapor stream passing therethrough; separating a condensed portion of the vapor stream with the supersonic separation device to provide a superheated vapor stream; passing the superheated vapor stream to a turbine, the turbine comprising a turbine wheel configured to transmit rotational movement to an electrical generator; rotating the turbine wheel with the superheated vapor stream; and, generating electricity with the electrical generator.
  • the present invention may be characterized as providing an apparatus for generating electricity which includes: a body with an inlet configured to receive a vapor stream, a first outlet for a superheated vapor stream and, a second outlet for a liquid stream; a baffle disposed within the body and configured to impart a swirl at or above sonic velocity to the vapor stream; an internal cavity in the body between the inlet, the first outlet, and the second outlet; and, a turbine wheel configured to transmit rotational movement from the superheated vapor stream to an electrical generator, the turbine wheel disposed between the outlet and the internal cavity.
  • Figure 1 depicts a partial cutaway schematic view of a device according to the present invention.
  • Figure 2 depicts a hydroprocessing unit according to one or more embodiments of the present invention.
  • the present invention provides a supersonic separating device upstream of a turbine.
  • the supersonic separating device condenses a portion of a vapor stream that is at or near its due point.
  • the remaining vapor portion, a superheated stream as a result of the heavier compounds being removed, is passed through the turbine, allowing the pressure to be reduced.
  • the turbine generates electricity from this energy dissipation which is recovered or used elsewhere in the processing unit.
  • the reduced pressure vapor stream is less likely to be a two-phase system and can be used as desired in the process unit.
  • FIG. 1 An exemplary device 10 according to the present invention is shown in Figure 1.
  • the device 10 is used for generating electricity and a vapor stream with a lower pressure.
  • the device 10 includes a supersonic separator 12 and a turbine 14. It is contemplated that the supersonic separator 12 and the turbine 14 are integrally formed as a single unit, i.e., the two are contained within a single body 15 (or housing) and are not connected to each other with any external conduits. This is merely a preferred configuration, and it is contemplated that the advantages and benefits of the present invention are achieved with the supersonic separator 12 and the turbine 14 being discrete components as opposed to a single unit.
  • the particular configuration of the supersonic separator 12 is not necessarily important for the practicing of the present invention.

  • the vapor stream 18 could be within 10 °C of a dew point of the vapor stream 18, within 5 °C of a dew point of the vapor stream 18, within 1 °C of a dew point of the vapor stream 18, or greater than the dew point of the vapor stream 18 but less than 1 °C from the dew point of the vapor stream 18.
  • the vapor stream 18 includes hydrogen gas and light hydrocarbons, hydrogen sulfide, ammonia, and water. By light hydrocarbons it is meant that the hydrocarbons in the vapor stream 18 comprise between one and six carbon atoms.

Downstream of the baffle(s) 26 the supersonic separator 12 includes an internal cavity 28. As is known in the art, within the internal cavity 28, the swirling vapor stream causes the larger molecules and compounds within the swirling vapor stream to condense together for form droplets. The droplets separate from the vapor and are recovered as the liquid stream 24 from the supersonic separator 12 via the second outlet 22. [00022] Downstream of the internal cavity 28, the vapor is a superheated vapor stream 20 that is passed to the turbine 14. The superheated vapor stream 20 has the same, or approximately the same temperature as the vapor stream 18.

  • the pressure of the superheated vapor stream 20 is reduced to provide a low pressure vapor stream 48 having a pressure that is less than the superheated vapor stream 20 (and the vapor stream 18).
  • the low pressure vapor stream 48 is less likely to be two-phase— even though the vapor stream 18 was at or near its dew point.
  • the present invention provides for the conversion of some of the energy removed via the pressure reductions to electricity.
  • the process according to the present invention comprises directing a portion of a gaseous process stream through one or more variable-resistance turbines to control the flowrate of the gas process stream and, optionally, generate electric power therefrom; controlling a pressure and temperature of the gaseous process stream so that the gas exiting the power-recovery turbine remains in the gas phase; and measuring the flowrate or controlling the flowrate or both using a variable nozzle turbine, inlet variable guide vanes, or direct coupled variable electric load, to name a few, to vary the resistance to flow through the turbine.
  • the resistance to rotation of the variable- resistance turbine can be varied by an external variable load electric circuit which is in a magnetic field from a magnet(s) that is rotating on the turbine.
  • An algorithm in the device can also calculate the actual flow through the device by measuring the turbine RPMs and the load on the circuit.

Abstract

Une turbine avec un séparateur supersonique est disposée en amont de la turbine. Le séparateur supersonique imprime un tourbillon sur un flux de vapeur pour éliminer tout composant plus lourd. Un flux de vapeur surchauffée provenant du séparateur supersonique est passé à travers la turbine pour réduire la pression du flux de vapeur. En même temps, de l'électricité est générée par le flux de vapeur surchauffée par l'intermédiaire d'une roue de turbine. La turbine et le séparateur supersonique peuvent être formés d'un seul tenant, ou ils peuvent être des composants discrets.
